Not supported

Any SDIO or USB devices are not supported, but work is ongoing to add that.

Known bugs/limitations

firmware does not support association to the same AP from different virtual STA interfaces (driver prints “ath10k: Failed to add peer XX:XX:XX:XX:XX:XX for VDEV: X” in that case)

packet injection isn't supported yet

applying ath9k regulatory domain hack patch from OpenWRT causes firmware crash (reason: regulatory hint function is never called and ath10k never sends scan channel list to the firmware which in turn causes firmware to crash on scan)

tx rate is reported as 6mbps due to firmware limitation (no tx rate information in tx completions); instead see /sys/kernel/debug/ieee80211/phyX/ath10k/fw_stats
